To all whom #may concern Be it known'that I, J AMES E. FLiToRor'i, acitizen ofthe United States, residing at Ocean Gro-ve, in the county ofMonmouth and. State of -NewjJerseyhave invented a new and usefullGrasolene Blow-Torch, of which the following isa spec'iication.

The present invention relates to improvements in gasolene blow torches,the primary is the provision of a novel form of air supthe chamber willbe tapered to a fine point to'v 'render the torch especially adapted'forbraz'- object of the present invention `being the provision of a blowtorch having a novel form of gas and air mixing means disposed inoperable relation to. thef'gasolene supply Valve, the said meansterminating in an'enlarged` cylindrical combustion .chamber having aflame reducing grid or baiiie, wherebyflame emitted fromI the combustioning andother workwhich requires the concentration of an intense heat. Afurther object of the present invention plying pump having mounted inthe lower end thereof a spring closed valve which prevents the entranceof the liquid or gasolene within the reservoir of the lamp fromenterplunger.

body or tank A still further object of the present invention is thenovel arrangement and positioning of a handle, said handle being`disposed at such an angle with relation to the torch as to render themanipulation or direction of the flame to the object to be heated moreeasilyfsaid handle'being so disposed as to render the manipulation ofthe torch more natural and so that the operator is permitted tor gripthev handle at an angle of substantially 45 or 'upright position of thetorch.

rwith the foregoing alia other pbjeasijin form of lockingv means'beingdis-- position, at WhichI time the.

degrees to the' body of view'which will appear as the descriptionproceeds, the invention resides in the comthe details of vconstructionhereinafter described and claimed, it being understood that `changes inthe precise embodimentv of invention herein disclosed can be made Withinthe scope ofwhat is claimed without departing from the spirit of theinvention.

In the drawingsnFigure l'is a vertical plete torch, the Valve being inlosed position, with the pump plunger locked in in ,most or down strokeposition.

Referring to the drawings, .designates the tank or reservoir which isoi. the usual construction and is provided with the hollow or arm .4being connected upon the same side 'of the tank or reservoir 1 as theboss 2, .andprojecting outwardly in a line parallel `with the bottom orlower edge of the tank and carryingremovably at its' upturned end 1l thegripping handle 5 whose upper end is 'held b'y .means of the lug 5Jformed integral with the yexterior of the boss 2, so

' A wick 11 is disposed in both of the tubes 7 and 10. By this means thegasolene Within the tank is iiltered as it is forced through the wick inthe tubes 7 and 10 to the torch body 14, thus preventing the burneufrombeing clogged and at the same time assisting in an even flow of gasolcneto the torch body 14, which is connected by means of its tubular boss tothe upper cud 12 ot' the standard l0, said standard 10`turtl1er Carryingthe drip cup 13. Mounted in the top of the tank or reservoir is aremovable cap G, whereby the tank may be filled with the gasolene orother iuid hydrocarbon.

The torch body 14 has formedtherein the liquid hydrocarbon conveyingchannels 16 and 17 which terminate in the concentrically disposedtapered outlet 1S controlled by a needle valve 19, the stem ot' whichvis mounted through the projecting end 20 and stutlng box 21 and isprovided with the operatingT wheel or handle F22. The fluid hydrocarbonunder pressure when supplied to the torch body is admitted from the endof the tapered bore 18 concentricall)7 of the enlarged air and gasmixing chamber 23, which is provided with the series of air inletelongated slots 24, said chamber being made substantially in the fornacitwo oppositely disposed truncated cones, whereby the air, due to theprojection ot thetlow or stream ot iluid hydrocarbon into theeductionftube or bore 25 of the main body 14, will be drawn through thelongitudi- ,nally disposed slots 24 and be thoroughly mixed within saidchamber and the eduction tube 25 before' the entrance of the carburetedair into the enlarged 'cylindrical combustion chamber 26 formed at theeX- treme' outer end ofv the torch body 14. Through the walls of thecylindrical combustion chamber are provided a plurality ofequidistant-ly spaced apertures 27, while mounted removably in the openend o' the vcombustion chamber is a disk' 28, which,

through the medium of the removable screws 29 .is fastened in the outerend of the combustion chamber, asclearly shown in Fig. 2. This disk isprovided with the concentrically disposed aperture 30- having radiatingtherefrom the plurality of radial slots 31, which provide a means forsplitting the partly burned gases, said disk 28 being a baille platewhereby'the flame due to the shape of the same and the radiating slots31 is caused to taper outwardly from the extreme end of the combustionchamber to an exceedingly sharp point, thus producing the desiredpointed vflame for brazing and other purposes.

In order to supply the properamount of air and the consequentpressure tothe contents of the tank or reservoir 1 to properly feed the' spray of`fiuid hydrocarbon into the torch body', the .removable pump cylinder 32is disposed within the bore of the boss, 2 of the lamp bodyhthe rim 33of said cylindrical pump body being disposed to receive the washer 33'and with the cap'or cover 34 properly seats the said pump within thebore and secures the saine air and liquid tight upon the upper extremeend of the hollow boss' 2 of the lamp. The removable cap 34 is providedwith the concentric aperture 35 through which is slidably mounted forrebeyond the plunger 39 is a concaved disk 40 ixed upon, to seal theupper end of the truncated conical casing 41 which is removably mountedin the concentric aperture in the lower end of the pump cylinder 32 andprojects within the body to be engaged or incased by the cupped portionof the concaved disk 40 when the plunger is locked in*vl the position asshown in Fig. 1. Formed coneent-rically and integrally with the innerend of the valve carrying casing 41 is the re-\ duced tube 42 formingthe air outlet for the pump and providing upon its lower. end a seat forthewalve 47 which is mounted within the removable tube 44, whose upperend is threaded intothe open end of the valve casing 41, said tube beingprovided -with the air outlet aperture 45 in its lower end and havingmounted therein the spring 46 which normally bears upwardly upon thelower side `of the valve 47 to hold the same in' valve seating positionwith the lower end of the, tube 42, a leather seat 48 being carried bythe valve 47. The said valve 47 is provided with the spring and spacedterminals 49 which ride upon thev wall of t-he tube 42 and therebyproperly guide the valve 47 into and out of seating relation and alsowhen forced downwardly', due to the in-stroke of the plunger 39, slidesdownwardly upon the stem 42 to permit the emission 'of air through the saces lbet-Ween the arms into the tube 44 and ignally into tank. By thisconstruction it will be seen that upon the downstroke of the plunger 39the air.will be forced within the tank or reservoir 1 and `that byreason of the spring 46 and the valve 47, that upon the up-stroke thepressure within the tank and the said spring will close the said valve'to prevent any leakage of air or the liquid into the `pump cylinder 32,thus preventing any action that tends to push the plunger upwardly intoextended position or'up-stroke, as is the general faultf with most blowtorches.

iso,

In order to lock the plunger in its downward position and.thereby placeit out 'of the way in manipulating the blow torch, the oppositely.disposed integral lugs 50 are formed upon the boss 2 while pivotallyconnected thereto is the bail 51, preferably'made of wire and providedwith the spaced terminals 52 with the eyes 53 u on the ends thereof,said eyes being pivota ly mounted upon the respective lugs 50, so thatthe coils 54 carried by the bridging portion of the bail 51 may bebrought into and out of contact as at a with the outer end of the buttonor handle 3S of the plungerstem, thus retaining the plunger stem in thedown .orinstroke position, and as the-said coil 54 permits a yieldingtension upon the upper end of the knob or handle 38, the said plunger 39is held yieldingly downwardly into valve se ting position, thus lockingthe same in an im# movable position and permitting the readymanipulation of the torch by means of the handle 5 withoutany'interference from the upper end of the plunger stem.
